88-Year-Old Minnesota Grandma Beaten, Stabbed to Death by Teen Grandson; Mom and Siblings Also Wounded in Attack

An 88-year-old Minnesota grandma was beaten and stabbed to death by his teen grandson at the family's home on Tuesday morning.

Crime Online reported that the 17-year-old boy also attacked several members of his family, injuring four more relatives. According to the Roseville Police Department, Minnesota grandma Patricia Frances Maslow was found dead at the scene from "sharp and blunt-force injuries."

Four other family members were injured in the attack, including the suspect's 55-year-old mom and 23-year-old sister. The teen's mom remains hospitalized, while his sister was already released after being treated for head trauma.

Police said the two other adult siblings suffered minor injuries. In an updated release on Wednesday, authorities said the Minnesota grandma died from injuries from a beating and stabbing from an unspecified weapon.

Teen Grandson Ran Off After He Stabbed to Death the Minnesota Grandma

According to the police statement, there were no police calls to the family's home at Roseville City in Ramsey County, Minnesota, and no documented police contacts with the teen suspect before the attack.

According to the Star Tribune, the motive for the attacks is still unclear. Police Chief Erika Scheider noted that a 911 caller inside the house said the boy was attacking other relatives and ran off.

After the teen ran away, the Ramsey County Emergency Communications Center sent out a "shelter-in-place" alert to mobile phones.

Alert for Fleeing Minnesota Teen Received Far Beyond the Intended Geographic Boundaries

Schools and businesses in Ramsey County went into lockdown late Tuesday morning after receiving the vague emergency alert with no location details.

At 10:50 a.m., cell phones in St. Paul and surrounding suburbs received the alert that stated "homicide suspect at large," and described the suspect as a 17-year-old white male.

According to the Lino Lakes Police Department, the emergency alert also reached the mobile phones in their town, which is about a 20 minutes drive from Roseville, Bring Me The News reported.

In a statement, officials in Ramsey County said the message was meant for mobile devices in a small area in Roseville.

"For reasons not known at this time, the Wireless Emergency Alert system pushed the message to a significantly broader area, and mobile phones across Ramsey County and nearby communities received the alert," the county noted.

At 11:15 a.m., a second emergency alert message advised individuals to shelter in the area of Larpenteur Avenue and Highway 36 and Snelling Avenue and Victoria Street.

After 15 minutes, a third message said the shelter-in-place order had been lifted as the suspect had been taken into custody. Ramsey County then apologized for the confusion and disruption the alerts caused "throughout the metro region."

"Ramsey County will continue to investigate this issue in the days ahead to identify the cause of the issue and prevent a similar incident from occurring in the future," the county said.

The teen grandson, who killed her grandma, was arrested roughly 40 minutes after the first emergency alert went out. The Ramsey County Prosecutor's Office is still investigating the case to decide on charges.
